Raïmgis

Literally meaning, "the
torn shield", the Raïmgis is a scar upon the planet and the very Realm of
IIo itself. The largest "rip" in the Aegis known, it allows demons to
pass through the Aegis with only the slightest lessening (proportional to the
power of the demon). The creation of the Aegis of the multiverse was one of the
greatest achievements in draconic history, and without it, IIo is effectively
defenseless.
